NASA’s Opportunity Mars rover found some rather peculiar rocks and minerals as it neared the end of its marathon study of the surface of the planet.

The rocks were found on a hill overlooking a site called “Marathon Valley,” named as such because Opportunity will have traveled 26.2 miles on Mars by the time it gets there.

2 dead, 20 injured after explosions at Boston Marathon today. Below is how CNN is reporting it...

Blasts near the finish line of the Boston Marathon killed two people and injured more than 20others Monday, Boston police said.

The marathon itself, on its Facebook page, referred to the blasts as bombs. Authorities did not say immediately what caused the explosions.

Massachusetts General Hospital said it was treating 19 injured people; Tufts Medical Center reported that it was treating nine people. Combined, that brings the number of injured to at least 28. Police reported 22 people injured.

The explosions sent smoke billowing into the air at Copley Square, turning a site of celebration into a mess of destruction.
